unable to connect managment node in NDB cluster (no replies)

Hi Guys,

I recently configured NDB cluster in my Lab environment with 2 Data nodes,2 SQL nodes and one management node on Microsoft Azure.
here I am facing some challenges while connecting to management node Below is the error message which I got .

ndb_mgmd --config-file=/var/lib/mysql-cluster/config.ini
MySQL Cluster Management Server mysql-5.6.28 ndb-7.4.10
2017-07-05 07:25:30 [MgmtSrvr] ERROR -- at line 7: Parse error
2017-07-05 07:25:30 [MgmtSrvr] ERROR -- at line 7: Could not parse name-value pair in config file.
2017-07-05 07:25:30 [MgmtSrvr] ERROR -- Could not load configuration from '/var/lib/mysql-cluster/config.ini'
2017-07-05 07:25:30 [MgmtSrvr] ERROR -- Could not determine which nodeid to use for this node. Specify it with --ndb-nodeid=<nodeid> on command line

And also I wanted to show the cluster status .I have ran the below commands, but it doesn't show anything about cluster throwing below error message..
[root@mngtnd ~]# ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show

Retrying every 5 seconds. Attempts left: 2 1

could you please let me know if anything missed by me .

Thanks in advance !!.
